T in whom, it may concern.-

Be it known that 1, WILLIAM DABB, mechanical engineer, a subject of the Queen of Great Britain, residing at Starcross, Oxford road, Oroydon, in the British Colony of Victoria, have invented an Improved Mop for Household and other Purposes having a Rotafollowing is aspeci fication.

The object of this invention is to provide a' mop the head of which can be rapidly rotated Within a bucket or other vessel in such a way that while a quantity of water can be driven out of it there will be no splashing, the Whole of such expelled water being intercepted by the sides of the bucket or other receptacle.

According to this invention the head of the mop is mounted or constructed upon a spindle Working in hearings in a clamp or holder and driven by bevel, friction, or other gear at any desired speed.

In order that the construction of the invention may be readily understood, it will be described by reference to the accompanying drawings, in which- Figure 1 is a side elevation of a rotatable mop and driving mechanism therefor c0nstructed according to this invention. Fig. 2 is a central section thereof on line '2 2, Fig. 1. Figs. 3 and 4 are views similar to Figs. 1 and 2, but illustrating the use of toothed bevel-gear for driving the mop instead of friction-gear and a slightly-different construction of mop. Fig. 5 is a sectional view showing a modification of a detail of the invention. Fig. 6 is a View similar to Figs. 2 and 4, illustrating a modified construction of my invention.

The same letters of reference indicate the same or corresponding parts in all the figures.

A represents the head of a mop, and B a spindle upon which said head is secured or I formed, while 0 represents a bearing on the end of a clip or socket D, fitted with a clamping-scre'vv E, whereby it may be clamped around a suitable wooden or other handle F. The lower end of this socket may be split, as shown at d in Fig. 1, and be adapted to be drawn tightly around the handle F by said screw, or a set-screwlE can be used, as shown in Fig. 3, the socket being made shorter and not split, this construction being preferred because itis cheaper and simpler. The spin dle B passes through a sleeve G, which is rotatable within the bearing Oon the end of the clamp or socket D.

One end of the spindle B is formed with a head I), while'its other end is screw-threaded to receive a butterfly-nut Z One end of the sleeve G is formed' with acup-shaped flange 9, into which the central portion of the head of the mop'is drawn by the spindle B. This cup shape allows the head of the bolt to be lscrewed up tight, so as not to come into contact' with the floor or whatever is being washed. The other end of the sleeve G is in the arrangement illustrated in Figs. 1 and 2 fitted with a bevel rubber-covered or other friction-pinion H, with which the correspond ingly-beveled face of a friction-wheel I on gages. This friction-wheel is mounted upon a stud J, upon or around which is a spiral spring K, whose tension can be adjusted by means of a nut k and which serves to keep the face of the Wheel I-in gearwith thepinion H.

The wheel I is'provided with a small crankhandle L, whereby it may be rotated so as to rotate the head of the mop at a rapid rate when desired, and said wheel is also provided with a set-screw M, whereby it can be firmly clamped against rotation, the set-screw being arranged to bear against a boss or flat N on the bearing 0.

With the above-described construction a new mop-head can easily be fitted in place of an old or worn one, it being merely necessary to screw ofi. the butterfly-nut b from the spindle B, withdraw the mop-head and spindle from the sleeve G, slip off the old mop-head, pass the spindle through a new one, and replace the spindle within the sleeve G, subsequently clamping everything tight by means of the nut 17. If preferred, a new mop-head can readily be constructed out of pieces ofcloth by threading them upon the spindle B and replacing said spindle and clamping everything up tight with the nut b, as illustrated in Figs. 3 and at. These figures also illustrate the employment of toothed bevelgearing H 1 instead of frictional gear, and they illustrate the use of a set-screw E instead of the clamping-screw shown in Fig. 1'. The pinion II is shown as integral with the sleeve G. In other respects the construction 'tary motion to the mop-head.

is substantially the same as above described, except that the spring K and its adjustingnut 70 are dispensed with, the wheel I being secured upon its stud J by means of a split pin and washer. If preferred, it may be secured by a set-screw fitted into said stud, as illustrated in Fig. 5.

It will be evident that many different kinds of mechanism other than those above described can be used for communicating a ro- If preferred, the sleeve and be made tapering, as illustrated at O G in Fig. 6, and the pinion can be fitted or castupon the end next the mop, as at H instead of on the opposite end. This construction is somewhat stronger than the other and provides more wear, while the pinionis not so liable to splash the water out of the bucket.

It will be obvious that a mop-head constructed as above described can be rotated at a rapid rate within the upper part of a bucketfor instance, after it has been dipped in the water or other liquid therein-and can therefore be dried to a sufficient extent without being touched by hand, thereby obviating the necessity for squeezingthe mop-head between the hands in order to wring out the superfiw ous, moisture.

its bearing can Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is--- 1. A mop forhousehold and other purposes, comprising a sleeve, a bearing in which said sleeve is rotatable, hand-operated gear for driving said sleeve, and a spindle passing through said sleeve and carrying the head of the mop.

2. In a mop for household and other purposes, having a rotatable head, the combination with a tapering sleeve, of a bearing in which said sleeve is rotatable, a hand-wheel carrying a bevel-gear, a spindle for carrying the mop-head, and a bevel-pinion on the end of the sleevenearest said mop-head and mesh ing with the gear on the hand-Wheel.

In a mop, the combination with a bearing, of a sleeve rotatable therein, a spindle passing through said sleeve, a hand-wheel for actuating the sleeve and spindle, and a set screw in the wheel adapted to bear against the side of said bearing to lock said wheel and prevent the mop-head from turning.
